FIELD OF THE INVENTION

The present invention is in the field of formulations, and in particular herbal formulations, for the management of symptoms of skin conditions.

BACKGROUND OF THE DISCLOSURE

Human bodies have evolved over millions of years in harmony with nature. Certain natural products induce the human body to function more efficiently at combating disease and adverse conditions. These products help the human body heal itself. Skin conditions, the most visible of human maladies, have historically received the most attention when it comes to the application of herbal remedies. Herbs have been used in the healing of adverse skin conditions for thousands of years. Aloe vera, for example, is an herbal extract that has been used throughout history as a skin soothant and healant. Even today, lotions containing aloe vera are used to help skin to heal after sunburn.

Despite advances in science, skin conditions remain prevalent and the alleviation of symptoms remains elusive. Humans must return to nature from whence they came to find suitable relief for these conditions.

When afflicted with an epidermal condition, the human skin naturally works to alleviate the symptoms of the condition. For example, in most cases, redness, itching, or scaling due to some disorders improve over time, or until the next episode of a flare up. The herbal preparations disclosed herein help the skin in its natural course to reduce the adverse symptoms. Without being bound to a particular theory, the present inventors believe that the present herbal preparations provide the skin with the nutrients and building blocks necessary to efficiently and effectively work to reduce the symptoms.

Thus, in another aspect, disclosed herein are methods of reducing symptoms associated with a skin condition in a subject, comprising identifying the subject in need thereof and administering to the subject an effective amount of an herbal preparation as disclosed herein.

In some embodiments, the symptoms associated with a skin condition include, but are not limited to, redness, itching, scaling, flaking, dry skin, acne, and the like associated with disorders such as acne vulgaris, psoriasis, eczema, or atopic dermatitis. In certain embodiments, the skin symptom is pruritis (itching), erythema (redness), or excoriations (flaking).

The term “subject” refers to an animal, preferably a mammal, and most preferably a human, who is the object of treatment, observation or experiment. The mammal may be selected from the group consisting of mice, rats, rabbits, guinea pigs, dogs, cats, sheep, goats, cows, primates, such as monkeys, chimpanzees, and apes, and humans.

The term “effective amount” or “therapeutically effective amount” is used to indicate an amount of an herbal preparation that elicits the biological response indicated. This response may occur in a tissue, system, animal or human and includes alleviation of the symptoms being treated.

In another aspect, disclosed herein are compositions comprising the herbal preparations disclosed herein and at least one physiologically acceptable excipient, diluent, or carrier.

The term “excipient” refers to a substance added to the compositions disclosed herein. In some cases, the herbal preparations disclosed herein may not by itself be easily administered and/or absorbed by the subject. In these cases the herbal preparations may be dissolved into or mixed with an excipient. Excipients are also sometimes used to bulk up formulations that contain the herbal preparations, to allow for convenient and accurate application. In addition to their use in the single application quantity, excipients can be used in the manufacturing process to aid in the handling of the herbal preparations concerned. Excipients also aid in stabilizing the formulations of the herbal preparations, for example by keeping the various ingredients in solution or in suspension, preventing precipitation or crystallization, or adherence to container walls.

The term “carrier” defines a chemical compound that facilitates the incorporation of a compound into cells or tissues. For example dimethyl sulfoxide (DMSO) is a commonly utilized carrier as it facilitates the uptake of many organic compounds into the cells or tissues of a subject.

The term “diluent” defines chemical compounds diluted in water that will dissolve the herbal extracts of interest and/or stabilize the formulation of the herbal preparations, including shelf life. Salts dissolved in buffered solutions are utilized as diluents in the art. One commonly used buffered solution is phosphate buffered saline because it mimics the salt conditions of human blood. Since buffer salts can control the pH of a solution at low concentrations, a buffered diluent rarely modifies the benefit of the herbal preparation.

Accordingly, disclosed herein are compositions and methods for the alleviation of the symptoms of skin conditions. The herbal preparations of the present invention can be delivered or administered to a mammal, (e.g., human subject), alone, or in the form of a formulated composition wherein the herbal preparation is mixed with suitable carriers or excipient(s) in an effective amount.

EXAMPLES Example 1: Herb Extraction

Procedure A:

Herb extraction was achieved by steam distillation. Optionally, one or more of the steps of oil separation, fermentation, hygroscopic salt extraction, and cohobation was added to the steam distillation step. The procedures were as follows.

Steam Distillation

Three liters of deionized water was poured into a 5 L distillation apparatus flask, which was then placed on a sand bath. Herb was added to the distillation apparatus flask until the flask was about half full. A filter paper was placed at the joint of the distillation apparatus before hooking up the reaction head adaptor. A 2 L receiving flask was used. Low heat was provided, sufficient for steam to cloud the distillation apparatus and adapter. After 1.5 L of distillate was collected, the heat was turned off and the apparatus was allowed to cool. The distillate was removed. One liter of deionized water was added to the distillation apparatus flask and the distillation was repeated. The distillation was repeated three times.

Oil Separation

The distillate, containing an aqueous phase and an oil phase, was transferred into a foil drain tube. The stopcock at the end of the drain tube was opened and the water was drained off into a 5 L flask.

Fermentation

Herb was placed into the 5 L flask containing the water after oil separation. The flask was sealed using a secure fermentation lock, and was incubated at 27° C. for two weeks. Subsequently, the water was distilled 5 times and the distillate was saved in a separate container.

Hygroscopic Salt Extraction

The remaining plant material was boiled until the moisture was evaporated and the plant material began to incinerate. Once the incinerated plant material became grey, it was removed from heat and allowed to cool. A Soxhlet extractor was used to extract the water soluble salts from the incinerated plant material. The salts were isolated by rotary evaporation. The extracted salts were placed in a calcining kiln at 600° C. for 1 week. The process was repeated for a total of 3 times.

Cohobation

The solution obtained after fermentation and the volatile oils were added to the isolated salts. The mixture was incubated at 30° C. for 1 week. The herbal-medicinal concentrate was separated without disturbing the sediment. The concentrate can be diluted as needed.

Procedure B:

Each individual plant raw material was subjected to steam distillation. After distillation the leftover material was in the form of wet mass. Additional water was added and the mixture was allowed to ferment in a glass container covered with a cloth lid. Fermentation was continued for 7 days at room temperature. During the fermentation the pH was monitored. Fermentation was allowed to continue until the mixtures began to putrefy. After the fermentation was over the biomass was filtered through a cloth filter and was subjected to distillation at 80-90° C. to get 30-40% of distillate of filtrate.

The leftover biomass was transferred to trays made from GI/MS and covered with cloth and was kept for drying in the shade. The drying was continued until the biomass became crisp dry, i.e., for about 15-20 days. During this time the material was turned around once in a day. After drying the material was subjected to ashing by either 1) burning the dry mass and collecting the cooled ash, which was then transferred to a crucible and heated further in an oven, or 2) incinerating the biomass by heating in a crucible at 600° C. The ash obtained is dissolved in distilled water and subjected to further distillation. All distillates were combined together and subjected to cohobation, where the combined product is heated under reflux for some time.

Example 2: Herbal Preparations

For the experiments detailed below, a unique herbal preparation (HAT-01) was used. Table 2 shows the herbs and their weight percentages within this formulation.

Furthermore, to compare constituent efficacy and synergism, HAT-01 was also partially formulated into two: HAT-01:P1 and HAT-01:P2 as described in Tables 3 and 4, respectively. These herbs have established clinical benefit, and are considered safe for clinical use in chronic inflammatory conditions.

Our NMR analyses of the ingredients in HAT-01 have confirmed the relative concentrations of components, and absolute concentrations of known substances. Of note, results from ¹H-NMR spectroscopic analyses of HAT-01 showed no evidence of a corticosteroid moiety, which correlates well with our findings that no changes were observed in serum cortisol levels in mice before and after treatment with 10% oral HAT-01, and demonstrating that HAT-01 effects are nonsteroidal.

Example 3: Benefits of HAT-01 in Patients with Psoriasis: Pilot Trial

To assess the benefits of HAT-01 in psoriasis, we performed an 8-week, open-label, two armed study (HAT-01 and OTC medication arm) in patients with mild to moderate chronic plaque psoriasis. Patients (aged 18 to 70 years) with stable chronic plaque psoriasis of at least 6 months duration with a psoriasis body surface area (BSA) ≦10% were included. All areas with the exception of the face, groin and axillae were treated. Patients with current or recent malignancies, severe asthma, infections, uncontrolled hypertension, and/or those treated with systemic or topical corticosteroid or immunosuppressant agents were excluded from the study. Patients with abnormal screening laboratory values, as well as pregnant women, were also excluded from the study. Patients were not allowed to use any medicated cosmetics that might influence the outcome of the study. A total of 16 patients fulfilling psoriasis inclusion criteria were enrolled into an exploratory 8 week, open-label study designed to investigate the safety, utility and tolerability of HAT-01. Patients were enrolled into one of two arms: (a) twice-daily application of HAT-01 (n=9 patients) or (b) twice-daily application of over-the-counter topical medications which are first-line therapy for patients with psoriasis and included topical vitamin D₃ analog calcipotriene or topical retinoids (n=7 patients). Approximately 300 μl of HAT-01 was applied per lesion, prepared as a 10% dilution of the concentrated herbal extracts in 4.9% EtOH. The primary outcome was defined as the percentage change from baseline in the body surface area affected by psoriasis at weeks 2, 4, and 8 following treatment. Safety evaluations included tolerability assessments and incidence of adverse events.

Patients were evaluated for changes in total body surface area, erythema, scaling, and plaque resolution. Patients with moderate disease activity who received HAT-01 demonstrated an average 42% reduction in the percentage in body surface area affected by psoriasis at 8 weeks, whereas those treated with a control OTC topical vitamin D₃ analog calcipotriene and topical retinoids exhibited a reduction in the percentage in body surface area affected by psoriasis by only 12% (FIG. 1). Significant resolution in erythema and scaling with changes in plaque elevation (from that of marked to slight) was observed in 8 of 9 patients after 8 weeks of HAT-01 treatment.

HAT-01 was well tolerated, with no treatment-related adverse events observed throughout the 8-week trial. At week 8, all patients treated with HAT-01 had no reports of skin atrophy, pruritus, or burning/stinging. In contrast at 8 weeks of treatment, 4 of 7 patients that were treated with control OTC topical vitamin D₃ analog calcipotriene exhibited local treatment-site irritation, burning sensation, and pain.

Example 4: Therapeutic Effects of HAT-01 in Patients with Acne Vulgaris: Clinical Vignettes

To assess the effects of HAT-01 in acne vulgaris, an open-label study of HAT-01 in subjects with mild to moderate (grade I and II) acne vulgaris was undertaken at an outpatient setting of a private practice clinic. Subjects aged 18 to 50 years of age with ≧three inflammatory or non-inflammatory lesions of papules or pustules in the face were included. Exclusion criteria included: severe acne, the use of any anti-acne medications within the preceding four weeks, or subjects with cystic lesions or any acne requiring systemic treatment. Subjects were not allowed to use any medicated cosmetics that might influence the outcome of the study. A total of 4 patients fulfilling criteria were enrolled. The primary efficacy outcome was defined as the change from baseline of the total lesion count. Subjects were asked to follow a 4 week regimen of twice daily applications of HAT-01 (300 μl applied per lesion, prepared as a 10% dilution of the concentrated herbal extracts in 4.9% EtOH). An analysis of the post-treatment inflammatory and non-inflammatory lesion counts demonstrated a highly significant reduction of scores from baseline to 4 week time points, indicative of the therapeutic potential of HAT-01 in acne vulgaris. HAT-01 was well tolerated, with no treatment-related adverse events observed throughout the 4-week trial including no reports of skin atrophy, pruritus, or burning/stinging at the local treatment-site.

Example 5: Clinical Studies

Methodology

The clinical trial was conducted in a contract research organization setting with three investigators (dermatologists) in a multi-center site. Patients were block randomized from a central location into each study arm. Patients were assessed both before and throughout the course of treatment at each visit using by SCORAD and a Patient Benefit Index (which assesses AD patient-relevant treatment benefit). SCORAD values, ranging from 0 to 103, are classified as mild (<15), moderate (16-40) and severe (>41), and are calculated as (0.2×Area)+(3.5×Erythema+Edema+Crust+Excoriation+Lichenification+Dryness)+(pruritis+sleep loss). All three investigators were given prior training and testing for standardized scoring of SCORAD in AD, an approach that has been found to be significantly beneficial for minimizing observer variability.

Our primary objective was the efficacy of HAT-01, HAT-01P1, and/or HAT-01P2 in the reduction of pruritus in atopic dermatitis patients.

Our secondary objective(s) were to

(a) evaluate the therapeutic benefit of HAT-01, HAT-01P1, and/or HAT-01P2 in atopic dermatitis as measured by the SCORAD (SCORing Atopic Dermatitis),

(b) evaluate the therapeutic benefit of HAT-01, HAT-01P1, and/or HAT-01P2 to reduce pruritus from patient's perspective as assessed by the Patient Benefit Index, and

(c) safety and tolerability of HAT-01, HAT-01P1, and/or HAT-01P2 in atopic dermatitis patients.

Double Blinded Randomization: A double blind approach where both investigators and patients are blinded was used. Investigators performed enrollment and blinded assignment using blinded labels. Assignments were rotated through enrollment by investigators to enable random continuous enrollment and avoid selection bias.

Treatment: Atopic dermatitis patients fulfilling eligibility (inclusion and exclusion criteria) were provided with an informed consent. A topical formulation of HAT-01, HAT-01P1, and/or HAT-01P2 was randomly and blindly provided (without patient knowledge) and followed through 2, 4, 8, and 12 weeks after treatment. Patients were assessed both before and throughout the course of treatment (each visit) for the following indices: SCORAD (SCORing Atopic Dermatitis), Patient Benefit Index. Each patient also had up to 10 mls of blood drawn prior to (0) and at 4, and 12, weeks post-therapy to distinguish laboratorial and cytokine changes over time. Serum from 64 patients with AD on an approved randomized single blind placebo-controlled clinical trial of HAT-01, placebo and partial formulations of HAT-01 were obtained for all groups at 3 time points (0, 4, 12 weeks).

Therapeutic Effects of HAT-01 in Patients with Atopic Dermatitis: Pilot Trial

To correlate our findings in human patients with AD, we performed an exploratory 10-week, open-label study to evaluate the utility of HAT-01 in atopic dermatitis. Significant resolution of symptoms and signs of AD was observed through a Three Item Severity score in 15 of 18 patients after 4 weeks of topical HAT-01 treatment, with no relapses at 10-weeks of follow up. We then performed pilot clinical studies to evaluate the utility of HAT-01 in atopic dermatitis. Patients with severe asthma and/or those treated with systemic or topical (greater than medium strength) corticosteroids or immunosuppressant agents were excluded from the study. An exploratory 10-week, open-label study was designed to investigate the safety, efficacy and tolerability of a twice-daily application of a topical formulation of HAT-01 in AD. A total of 18 patients fulfilling diagnostic criteria for AD were enrolled and placed on a regimen of twice daily application of a topical formulation of HAT-01 (300 μl of 1:10). FIG. 2 portrays the design outline of this pilot trial. The primary efficacy outcome was defined as the change in the Three Item Severity score (TIS score) of AD based on the evaluation of erythema, oedema/papulation and excoriation in each representative lesion. Significant resolution of symptoms and signs of AD was observed in 83% of patients (15 of 18) after 4 weeks of HAT-01 treatment, with no relapses at 8-week or 10-week follow up (FIG. 3). Patients with severe disease activity pretreatment (TIS score>6) demonstrated an average 54.6% reduction in disease activity at 4-weeks, and an average of 77.1% reduction in disease activity by 10-weeks (FIG. 3). Of note, a significant reduction in edema and erythema was observed within 2-weeks, which was followed by improvements in oozing and excoriations within 4 weeks following treatment with HAT-01. Significant improvement in xerosis (dryness) was also immediately observed, while improvement in lichenification (thickening) took up to 10 weeks for effective resolution.

AD: Therapeutic effects of HAT-01 in patients with atopic dermatitis: Randomized placebo-controlled trial. To further investigate the safety, efficacy and tolerability of a twice-daily application of a topical formulation of HAT-01 in atopic dermatitis (AD), a total of 64 patients fulfilling inclusion criteria for AD were enrolled into a randomized placebo-controlled single (patient) blind clinical trial with a regimen of twice daily application of a topical formulation of HAT-01 (300 μl of 1:10). The primary efficacy outcome was defined as the change in the Severity Scoring of Atopic Dermatitis (SCORAD) values. SCORAD values, ranging from 0 to 103, are classified as mild (<15), moderate (16-40) and severe (>41), and are calculated as (0.2×Area)+(3.5×Erythema+Edema+Crust+Excoriation+Lichenification+Dryness)+(pruritis+sleep loss). As shown in FIG. 4, significant resolution of symptoms and signs of AD was observed in 84% of patients after 4 weeks of HAT-01 treatment, with sustained effects and no relapses at 8-week or 12-weeks of follow up (FIG. 4). Placebo (vehicle) treatment had no significant effect on SCORAD values, and treatment with partial formulations HAT-01:P1 and HAT-01:P2 had only minimal effects relative to treatment with whole HAT-01 (FIG. 4). Significant reduction in edema and erythema was observed within 4-weeks, which was followed by improvements in oozing and excoriations within 8 weeks following treatment with HAT-01. Significant improvement in xerosis was also observed at 4 weeks, while improvement in lichenification took up to 12 weeks for effective resolution. Importantly, HAT-01 was well tolerated and no treatment-related adverse events were observed throughout the 12-week pilot trial, indicating the safe and potent therapeutic benefit of HAT-01 in a majority of the patients studied with AD.
